20 # carbon steel cold stamping rebar coupler for construction use
?
Product Description:
# Cold stamping rebar coupler is made of quality seamless steel tube which has good rolling performance. And it has reliable performance and dimensionally stable.
# Squeeze splicing don’t change the original size and performance of the rebar. Our rebar coupler has a reliable performance, which is same as the base metal, having reached grade I performance of JGJ107 provisions.
# Cold stamping rebar coupler is used toghther with cold stamping machine-this?splicing device has advantages of?high speed, long life, less failure, are national key and new products

?
Advantages:
# Reliable performance and dimensionally stable.
# Grade I performance of JGJ107 provisions.
# Easy operation, QC convenient, no construction risk.
# Save cost.
# Wide range of applications.

Tensile test for the cold stamping rebar splice

1. 500pcs same size rebar splices as one batch, remained less than 500pcs also as one batch. Pick 3pcs from each batch to do tensile test, the length of tested rebar splice should be around 0.8m.

2. The tensile strength of all the 3 rebar splice samples should be higher than rebar standard tensile strength*1.05 or bar break.

3. If one of the 3 rebar splice samples tensile strength below the requested data(1.05*rebar standard tensile strength), should pick double quantity rebar splice samples to recheck. If there is still one sample tensile strength below the requested data, then the batch is not qualified.

4. Better to choose samples randomly from the construction site rebar splices. If condition doesn’t permit, also could produce the same samples as construction site.
